#59119 I'm sure you've found the answer already, but for future readers: when I bumped into this problem I solved it by using shorter wires between my UART and the ESP8266. The problem appears to be caused, as you might expect given the error message, by signal integrity problems.

#60454 I can confirm that. I had my cables extended to reach the USB port, but when I shortened them back, the write_flash went successful.
